Is It Safe to Drive With the Washer Fluid Level Light On?
Whether it is safe to keep driving your Isuzu MU-X with the Washer Fluid Level Light on comes down to urgency (low) and behaviour. As a rule, if the light is red or flashing, or the Isuzu MU-X is running poorly, stop somewhere safe and arrange help rather than pushing on.

Professional Mechanic Tips
Use a proper screen-wash mix in a Isuzu MU-X, not plain water — water freezes in winter and grows algae that blocks the jets.
If the light stays on with a full tank, tap the reservoir; a stuck float sensor often frees up, otherwise it is a cheap sensor swap.
